I run 35's and my rig hauls ass but I have 17" wheels.

None, stock 3.73 pull fine. I doubt your Z71 hoe came with 3.42 gears but optional were 4.10. So if you're running 33x12.50 and feel slow get a set of 4.10 and 4.56 if lifting on 35s

What size gears are u currently running ? Look in the glove box at the build sheet taped to the inside of the glove box gt4=373 and gu6 =342. If u have 373 gears you should be fine however if you do in fact have 373 gears and she still feels slugish you could bump it up to 410 but be prepared to do both front and rear on a 4x4

You should have 3.73 in there now. I would think 33s would be just fine with 3.73. If you need more - look into getting a tune before gears... cheaper for one, and it may be just what you need.
